foreach loop syntax in javascript -

consider myarray array of objects.

are these 2 pieces of code equivalent ?

myarray.foreach((item) => {   return doanaction(item); });   myarray.foreach((item) => {       doanaction(item);     }); 

is there of them better in terms of syntax? if yes, why ?

the better question is, why not use function directly callback, like

myarray.foreach(doanaction); 

the callback must follow api of array#foreach, is

function execute each element, taking 3 arguments:

• currentvalue: current element being processed in array.
• index: index of current element being processed in array.
• array: array that foreach() being applied to.

if need element, use given callback directly without mapping.
